I have a big problem using qmail.
Only the first 52 addresses out of 620 get an email
when I send a mailing to myMailingList@lists.myDomain.com.
Does anyone know a sollution or the problem ?

Where can I read more about using the qMail interface ?
I would like to see some good structured docs about
the tool. The official site is to confusing for me to
work with ... I'm not working for a hosting company,
i'm using a server to host my site, so i just need
information about how to use the admin panel.

Look at life with qmail, probably the best place to read up on qmail:

Also, look at "the big picture" to see how all the programs interact with each other, and learn how a message goes through qmail:
